FISHING JOB : EQUIPMENT, OPERATION, AND APLICATION
The term fishing
applies to all operations concerned with the retrieving of equipment or other
objects from the hole. Portions of the drill string, bit, drill string
accessories, and inadvertently dropped hand tools are typical items which may
require fishing. The most common fishing job is that recovering of a portion of
the drill string left in the hole due to either its failing or becoming stuck.
The best fishing
technique is elimination of the cause. Periodic equipment inspections minimize
drill string failures by detecting faulty joints before they fail. The
alertness of the drilling crews in detecting
crooked joints, in cleaning and lubricating tool joint threads properly,
and in exercising good house keeping and safety precautions, fishing jobs
do occur frequently. Most of them are
relatively simple, and the only lost is the time required to run the fishing
tool and retrieve the fish. A few such jobs however, become extremely costly
and time consuming and even result in the loss of the hole.
